ISAAC N. JOHNSON, OF TIPTON, INDIANA:
SPRAYER.
SPECIFICATION forming part of Letters Patent No. 637,798, dated November 28, 1899- Application filed June 19, 1899. Serial No. 721,099. (No model.)
To all whom it may concern:
Be it known that I, ISAAC N. JOHNSON, a citizen of the United States, residing at Tipton, in the county of Tipton and State of Indiana, have invented a new and useful Sprayer, of which the following is a specification.
This invention relates to sprayers for spraying an insect-destroying liquid on plants and the like, and has for its object to provide a simple and improved device which may be carried in one hand and is adapted to draw the liquid from a bucket or other receptacle and discharge the same in the form of a spray.
The device embodies in its construction a cylinder having aninlet and a discharge opening, the former having a connection with the liquid to be sprayed and the latter having a spraynozzle, through which the liquid is adapted to be discharged. The means for drawing the liquid into the device and discharging the same therefrom comprises a plunger or piston working in the cylinder and operated by means of a lever, so that the plunger is completely under the control of the operator and the spraying operation may be immediately stopped at any time, whereby the liquid may not be wasted.
To these ends the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and the minor details of construction may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the present invention.
In the accompanying drawings, Figure l is a perspective View of the improved sprayer. Fig. 2 is a longitudinal sectional View thereof. Fig. 3 is an enlarged detail top plan view of the base of the device. Fig. 4 is a detail perspective View of the valve.
Corresponding parts in the several figures of the drawings are designated by like characters of reference.
Referring to the accompanying drawings, 1 designates the base of the device, which is provided with an upstanding ring or cup 2, which is internally threaded and adapted to receive the lower externally-threaded portion of the cylinder 3. At diametrically opposite points and below the cup or ring 2 the base is provided with an inlet-opening 4 and an opposite discharge-opening 5, and projecting outwardly in opposite directions from the respective openings are the externally-threaded tubes or nipples 5 and 6, respectively. The inlet and discharge openings are separated by means of a wall or partition 7, and said openings communicate with the interior of the cylinder by means of the openings 8 and 9, respectively, which are formed through the top of the base and located adjacent to the opposite sides of the partition 7. Each of these openings is controlled by means of valves, which are formed bya leather or other flexible disk 10, which is fitted snugly within the lower end of the cylinder and rests upon the top of the base, thereby closing the openings 8 and 9. As best shown in Fig. 4, it will be seen that the disk is provided with opposite arcuate slits, which form the flap-valves 11 and 12, respectively, which are located immediately over the respective openings 8 and 9 and are adapted to work in opposite directions by means of a metallic disk 13, which rests upon the top of the valved disk and is provided with a substantially large and semicircular opening 14 and asmaller circular opening 15, located opposite the former opening. It will be noted that the opening 8, which communicates into the interior of the cylinder, is smaller than the other opening 9, and the disk 13 is arranged so that its large opening 14 is over the smaller opening 8 and its smaller opening 15 is above the larger opening 9. Thus it will be seen that the flap-valve 11 is adapted to work upwardly through the large opening 14 in the disk 13, and the opposite fiap-valve 12 works downwardly through the large opening 9 in the top of the base, so that said valves are caused to work in opposite directions and are held against reverse the latter and the valved disk firmly in posi tion and effectually preventing accidental displacement thereof.
The base 1 is provided with a suitable handle 16, extending rearwardly beneath the nip ple5, and is provided intermediate of its ends with a pair of opposite pendent cars 17, between which is'pivoted a lever. 18, which is alined longitudinally beneath the handle.
This lever is pivoted near its forward end, so
as to provide a comparatively long operatinghandle therefor, .and a. suitable spring 19 is interposed between, the handle of the sprayer.
coil 21 is located at the opposite connecting ends of said arms.
Located within the cylinder 3 is a suitable plunger or piston 22, which is provided with a rod 23, projecting upwardly above the top of the cylinder, and is operatively connected to the adjacent end of the lever 18 by-means this link is pivoted, as at 25, to the upper-end of the rod 23, the opposite sides of the link extending downwardly, embracing the cylin-' der and base, and pivotally connected, asat 26, to the adjacent end of the lever 18. The
. upper end of the cylinder 3 is closed by means of a screw-cap 27, having a central opening '28 loosely receiving the plunger-rod 23 and forming a guide therefor.
Connected to the inlet-nipple 5* is a suitable flexible hose or pipe 29, the opposite end of which is adapted to be submerged in a bucket or suitable receptacle containing the insect-destroying liquid, and the dischargenipple- 6 is provided with'a suitable spraynozzle 30, through which the liquid is adapted to be discharged and formed into a spray".
In the operation of the device the handle 16 and the adjacent portion of the lever 18 are grasped by one hand of the operator, and by forcing the lever 18 toward the handle 16 the plunger 22 is forced downward within the cylinder, and when the grip of the hand is released the lever will be forced away from the handle by means of the spring 19, thereby raising the plunger. When the plunger is being drawn upward, a suction is provided which draws the liquid through the pipe 29 and the inlet 4 and is discharged through the small opening Sin the top of thebase and the larger opening 14 inthe disk 13 and into the interior-of the cylinder. It will beu-nderstood that the fiap-valve 11 opens upwardly into the large opening 14 in the disk 13, so as to-facilitate the passage of the liquid upwardly and into the cylinder; but upon the return downward stroke of the plunger said valve will also be forced downward against the top of the. base and thereby close the small opening 8, thus preventingthe liquid from being forced backward through the tube 29 and into the bucket or receptacle. When the plunger 22 descends, the flap-valve 12 will be forced downward through the large opening 9 in the top of the base and the liquid will be forced from the cylinder through said opening to the spray nozzle 30, from which it will be dischargedin the form of a spray. Upon the upward return stroke of the plunger the flapvalve 12 will close against the under side of the disk 13, so as to prevent the return of the liquid into the interior of the cylinder.
By the continued operation of the lever 18 the liquidwill be'alternately drawn from the .bucket or receptacle into the cylinder 3 and discharged therefrom through the spraymozzle 30, the valves 11 and 12 efiectively preventing the return of the liquid in opposite directions. Furthermore, it will be understood thatso long as the lever 18 is not in motion the plunger 22 will not be operated, and therefore the liquid will not be either drawn from the receptacle or discharged through the spray-nozzle, whereby the discharge of the liquid may be immediately stopped at any I 'time, so as to prevent waste of the liquid. of a yoke-shaped link 24:. The upper'end of The; several parts of the present: device are removably connected together, as hcreinbefore described, so that the device may be readily taken apart for cleaningor replacing any broken parts; Also the cylinder may be unscrewed from the ring or cap 2, and by reason of, the pivotal connection between the upper end of the plungerrod and the link 24 the cylinder may be swung clear of the cup or ring, so as to permit the removal of the plunger therefrom without disconnecting the link 24. This detachable connectionbetween the cylinder and the cup or ring 2 provides convenient access to the disks 10 and 13, so that the same may be replaced when worn or damaged and also may be adjusted so as to properly aline the openings of the metallic disk with those of the base and also with the flap-valves.
What I claim is-- 7 1. In a sprayer, a pair of hand-operated levers pivoted orhinged intermediate of their ends, a spring interposed between the lovers, located at one side of the pivotal connection thereof, and normally holding together the opposite ends of the levers,.a pump-cylinder carried by the latter end of one of the lovers, and provided with valves, a plunger, and a plunger-rod projecting through the outer end of the cylinder, links connected at opposite ends to the projecting end of the plunger-rod, and to the adjacent end of the other lever, and located at opposite sides of the cylinder,
,aflexible inlet-tube in connection with the pump-cylinder, and a dischargespray-nozzle also in communication with the cylinder, substantially in the manner shown and described.
'2. In a sprayer, the combination,with a pair of spring-actuated levers pivotally secured together near one end, of a base secured to the shorter end of one of the levers, said base being provided with two nipples and an annular flange, said nipples being located diametrically opposite each other and in alinement with the levers, each nipple being perforated longitudinally, the inner end of each perforation lying in the top of the base and within the flange, a flexible tube secured to one of the nipples, and a sprinkler secured to the other one and projecting beyond the ends of the levers, a cylinder secured to the flange,
a piston and valves therein, and links for connecting the piston with the end of the secondmentioned lever.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two Witnesses.
ISAAC N. JOHNSON.
